Modern land-based gas turbines can prove intimidating indeed when it comes to understanding the myriad of alloys and coatings, and their idiosyncrasies, which are used for critical components. For the turbine user wanting to optimize combustion and hot section component life, Eta Technologies LLC (ηTech) can help you handle the following vital questions and issues:

  • Do I clearly understand the degree of metallurgical deterioration that occurs in my parts during their service intervals?
  • Are the metallurgical changes or damages that take place reversible or irreversible?
  • Am I handling how I repair and coat my parts in the best metallurgical way?
    • Can I get metallurgical help with my repair and coating specifications?
    • Are the steps and processes used by my repair vendor the right ones to optimize metallurgical rejuvenation?
    • Are there heat treatments that can be used to optimize repairability, thus maximizing my repair yield, that are compatible with the cycles to restore material properties?
    • Are there improvements, such as a better coating or blade tip repair method, tailored to my operating conditions that can be implemented during repair?
  • If I want to purchase or make re-engineered parts, have the metallurgical details been properly captured?
    • Am I sure that the best the best alloys and coatings have been selected?
    • How can I work around patented alloys or coatings?
    • Have alloy, coating, and inspection specifications been properly defined?
    • Have the manufacturing suppliers met the metallurgical requirements?

With decades of experience in gas turbine metallurgy, ηTech can provide the assurance that regardless of the specifics of my parts management plan, there are no worries over the “black box” of metallurgy.
